Electronic configuration of an element is \( 1 \mathrm{~s}^{2}, 2 \mathrm{~s}^{1}, 2 \mathrm{p}^{2} \). It is:
(a) Ground state configuration of \( \mathrm{B}(\mathrm{Z}=5) \).
(b) Excited state configuration of B.
(c) Ground state configuration of \( \mathrm{C}^{+} \)ion \( (\mathrm{Z}=6) \).
(d) Impossible configuration.
